Depends on the usage, I suppose. I wouldn't use it for tactical, as it really is a tiny little tube to look through (20mm or close to, if I remember correctly). $50 seems to be the going rate for one on GB; ironically, that is about what I sold mine for. Give it a good look over and check for parallax issues and dot sharpness. Also take into consideration that it has been discontinued for some time now, so parts/repairs might not be an option.
